摘要
应用微型反应量热仪对某型改性双基推进剂的比热容进行测定.根据实际需求和被测物性质,推进剂比热容测定温度选为298K,323K,348K,358K和368K,实验数据标准偏差均小于3%.实验过程中,推进剂发生分解,其减少的质量约占原质量的0.6%.通过origin软件对实验数据进行拟合,得到推进剂比热容关于温度的函数关系式.同时,利用比热容方程计算以298K为基础的该型改性双基推进剂热力学函数.
The specific heat capacity of one modified double-base propellant is determined with the micro reaction calorimeter.In consideration of the actual demand and the properties of tested agent,temperatures of 298 K,323 K,348 K,358 K and 368 K are chosen for the experiment.The standard deviations of the experiment data are less than 3%.During the experiment,the propellant decomposed and the loss of the mass was 0.6% of the original.The software origin was used to fit the data and obtain the relationship of the specific heat capacity and temperature.Based on the data above,thermodynamic functions are calculated.
